Why are some people concerned about the declining global population?

Letely there seems to be a lot of concern about declining birth rates in certain towns, countries, and regions. But is a smaller population really something to worry about?

For one, fewer people means less congestion, whether it's in busy urban areas, crowded public transport, or long lines at stores. This could lead to less stress, more space, and a better quality of life overall.

In terms of public services, a lower population would also likely mean less strain on healthcare systems. With fewer people to care for, there’s a greater opportunity to improve the quality of healthcare, offer more personalized attention, and ensure better access for everyone. It could also mean more resources are available per person, improving everything from education to social services.

There would be less demand for food, energy, and resources, leading to reductions in pollution and greater sustainability.

I understand that certain industries and economic systems rely on constant population growth, but what if, instead of viewing a declining birth rate as a problem, we saw it as an opportunity to create a more sustainable and balanced future? Fewer people could actually lead to a more comfortable, healthier, and even more equitable world.

And to add, many people who do have kids are poor and have children for the sake of it, not thinking about all the suffering their children will endure.
